orrI BURNER.

Application led Mayr15, 1926. i Serial No. 109,385.

'Ihis invention relates to an oil burner.

An object of the invention is to :provide a burner of such construction that the deposition of carbon on the surfaces ofthe burner is reduced toa minimum.

A further object resides in the provisio of a simple and eilicient means whereby the burner plate can be quickly and easily preheated before theA oil is turned on.

A further objects resides in the provision of a simple and efficient construction whereby when thevoil is turned oil' there will be no residue left in or on the burner.

The invention is illustrated in the drawings, of which- Figure 1 isa vertical section through the device; y

Figure 2 is a horizontal section on the line 2 2 of Figure 1;

Figure 3 is a horizontal section on the line 3 3 of Figure 1;

Figure 4 is a section through the burner plate proper.

The form ef the invention shown in the drawings is a preferred form, although it understood that modilications in the construction and arrangement of the parts and in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the Vappended claims.

In its general aspect the invention co1nprises a burner plat-e preferably somewhat conical in shape and corrugated, having an oil inlet near its apex through which o-il is fed to the top of the plate and from which it flows downwardly over the plate. The burner plate is spaced above a similarly shaped plate which receives the oil and which I shall call a spill plate. Any oil which is not burned runs down on the spill plate and collects in a groove er channel at the bottoni at the outer edge thereof and passes off through a discharge pipe. Suitable air conduits rise on either side of the spill plate and project air downwardly on the top of the burner plate. I preferably provide, beneath the burner plate, an auxiliary nozzle through which gas or some other heating medium may be introduced as an auxiliary means whereby the under surfaces ofthe burner plate can he brought to a proper temperature before the main supply of oil is turned on. It is of course to be understood that any other suitable means for heating the under surface of the burner plate can be employed. I also provide an outlet in the main oil pipe beneath the burner plate so that a small quantity of the main oil supply can be tapped oif beneath the plate and ignited for the purpose of preheating the plate when desired.

Preferably the central portion of the spill plate is formed in a cup shaped manner tol enable it to receive a small quantity of oil for thepreheating purposes above mentioned. rI'his cup, however, is'provided with a discharge pipe so that only a niinimum auxiliary supply ofioil can be kept in the cup. A

In the preferred form of the invention shown in the drawings I provide a spill plate 10 preferably substantially cone shaped and having a peripheral groove or trough 11 from which discharge pipe 12 extends. The central portion of the spill plate 10 is provided with a cup 13 in the bottoni of which is a boss 1li through which an inlet pipe 15 extends. An` auxiliary fuel pipe 16 also extends through the bot-tom of the ciu. The cup isprovided with a discharge pipe 17 leading to the spill plate.

From opposite sides of the spill plate air conduits 18 and 19 rise and extend toward each other, meeting over the center' of the spill plate with their upper passages pointing downward. Spaced above the top of the spill plate is a burner plate 20, preferably somewhat cone-shaped and provided with corrugations 21. The burner plate rests on the spill plate on legs 22. The inlet pipe 15 extends through the center of the burner plate and is provided on its upper end with a nozzle 23. Oil issues from this nozzle. Above the nozzle is disposed a baille or dei'lector pla-te 2l. The side of the main oil pipe 15 is provided with a plug valve 25 beneath the burner plate.

In the operation of the device, it is sometimes desirable to feed auxiliary fuel, such as gas, through the pipe 16' and ignite it heneath the burner plate 2O while a small supply of eil is turned on. rl`his will preliminarily heat the burner plate to the desired temperature before the niain oil supply is turned on. Instead of using gas the plug 25 can be slightly opened to allow a. little of the main oil supply to flow into the cup 13. This oil can then be ignited to preliminarily heat the burner plate. Any excessive quantity of oil in the cup will flow oft through the pipe 17. After the burner plate has been proplill erly heated, the main oil supply is turned on, pouringout of the nozzle 23 and down over the top of the burner plate, which, being sufficiently heated, will cause the oil to burn. The air passing up through the casings 18 and 19 will be deected downwardly on the oil to form a proper mixture. Any excess oil which is not burned will flow down the spill plate to the trough 11 and pass out through the pipe 12.

Vhat I claim is:

1. An oil burner which comprises a spill plate, substantially conical in shape, having a central cup anda peripheral groove, a discharge pipe connected to said groove, a substantially conical shaped burner plate disposed above the spill plate, an oil feeding pipe leading to the center of the burner plate and adapted to feed oil to the top of the burner plate and means between the two plates for permitting oil to flow from the oil feeding Ypipe into the cup of the spill plate whereby the yunder surface of the urner plate may be preliminarily heated.

2. An oil burner which comprises a. burner passing upwardly through the spill plate to Y the burner plate to feed oil to the top of theV burner plate and provided with an opening between the said plates, and, a. plug controlling the opening in the feed'pipe to permit oil to How from the pipe into the cup of the spill plate. Y Y

3. An oil burner which comprises a substantially conical shaped corrugatedv burner plate, a substantially conical shaped spill plate having a cup in the center thereof and a peripheral groove, a discharge. pipe'connected to the groove, a discharge pipe connected to said cup and leading to the surface ofthe spill plate, an oil feeding pipe passing up through the spillv plate to a point above the top of the vburner plate,said oil feeding pipe having an opening between the said plates, and a plug controlling the opening in the said pipe to permit oil 'to be admitted to the cup of the spill plate.
